This May Raise Dementia Risk in Seniors With Diabetes

Overly aggressive glucose control might backfire in older patients, findings suggest

continued...

For the study, Yaffe's team collected data on 783 diabetic patients who were aged 70 to 79 and free of dementia at the start of the study in 1997.

Over 12 years of follow-up on average, participants were periodically given tests of mental ability.

The researchers found people who were hospitalized for severe hypoglycemia had twice the risk of developing dementia compared with those who didn't have bouts of hypoglycemia.

And patients with dementia were also more than twice as likely to have severe hypoglycemia, they found.

Based on the findings, Dr. Marc Gordon, chief of neurology at Zucker Hillside Hospital in Glen Oaks, N.Y., said he thinks trying to control blood sugar too aggressively might be ill-advised.

"There has been a concern about the association between diabetes and dementia, Gordon said. "Patients need to be careful that they are not either undertreated or over treated and that they monitor their blood sugar," he said.

Your level is currently

If the level is below 70 and you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
